Spreadsheets for Analyzing and Optimizing Space Missions

Thursday, 26 February 2009

XCALIBR (XML Capability Analysis
LIBRary) is a set of Extensible Markup
Language (XML) database and spreadsheet-based analysis software tools
designed to assist in technology-return-on-investment analysis and optimization
of technology portfolios pertaining to
outer- space missions. XCALIBR is also
being examined for use in planning,
tracking, and documentation of projects.
An XCALIBR database contains
information on mission requirements
and technological capabilities, which are
related by use of an XML taxonomy.
XCALIBR incorporates a standardized
interface for exporting data and analysis
templates to an Excel spreadsheet.
Unique features of XCALIBR include
the following:

It is inherently hierarchical by virtue of
its XML basis.

The XML taxonomy codifies a comprehensive
data structure and data
dictionary that includes performance
metrics for spacecraft, sensors, and
spacecraft systems other than sensors.
The taxonomy contains >700
nodes representing all levels, from
system through subsystem to individual
parts.
